You eat food and drink water, right? Skipping Rocks Lab is changing how you and your future generations will have water. Have you ever thought you could eat water? Think again, this is actually happening somewhere in the world.

    The group at Skipping Rocks Lab has made a water bottle you can eat. The product is called Ooho. Unlike plastic bottles, Oohos are neither tall nor hard. They look more like bubbles, or small, round, clear balls. They can hold liquid inside. People who drink Oohos can be surprised: the outside bursts in the mouth.

    Rodrigo Garcia Gonzalez is with Skipping Rocks Lab. He explains that the outside, or the membrane, of Ooho is made of seaweed, a plant that grows in the ocean. “It's a membrane made of seaweed that can contain water or any kind of liquid. It's made from an extract (汁) of the brown seaweed.”

    The Ooho membrane is tasteless, and you can eat it. The company says even if you throw away the membrane, it will break down in about four weeks. Gonzalez says the membrane is strong, and good for the environment.

Every year, billions of plastic water bottles are thrown away, polluting land and waterways around the world. The typical water bottle made of plastic can take hundreds of years to degrade.

    Lise Honsinger is also with Skipping Rocks Lab. “Most people just grab a bottle of water, hold it for five minutes, drink it, and throw it away. How can that then exist for 700 years? So, yeah, this is absolutely a solution to that. We are very purist: we don't want to see this packaged in plastic.”

    There are limits to the Ooho. It cannot be refilled. Each bottle is small. And Oohos do not store for more than a few days. The Skipping Rocks Lab is working on those issues. “We're still working on things like extending the shelf life, looking at different options in terms of thickness, if we want to make one that stands up more, or more flexible for marathons where people just want to eat it whole.”

    Right now, Skipping Rocks Lab can make only a few thousand Oohos a day. But it is developing new technology that could increase that number to hundreds of thousands.

    One day, when I was working as a psychologist（心理学家）in England, an adolescent boy showed up in my office. It was David. He kept walking up and down restlessly, his face pale, and his hands shaking slightly. His head teacher had referred him to me. “This boy has lost his family,” he wrote. “He is understandably very sad and refuses to talk to others, and I'm very worried about him. Can you help?”

    I looked at David and showed him to a chair. How could I help him? There are problems psychology doesn't have the answer to, and which no words can describe. Sometimes the best thing one can do is to listen openly and sympathetically（同情）

The first two times we met, David didn't say a word. He sat there, only looking up to look at the children's drawings on the wall behind me. I suggested we play a game of chess. He nodded. After that he played chess with me every Wednesday afternoon—in complete silence and without looking at me. It's not easy to cheat in chess, but I admit I made sure David won once or twice.

    Usually, he arrived earlier than agreed, took the chess board and pieces from the shelf and began setting them up before I even got a chance to sit down. It seemed as if he enjoyed my company（陪伴）. But why did he never look at me?

    “Perhaps he simply needs someone to share his pain with,” I thought. “Perhaps he senses that I respect his suffering.” Some months later, when we were playing chess, he looked up at me suddenly.

    “It's your turn,” he said.

    After that day, David started talking. He got friends in school and joined a bicycle club. He wrote to me a few times, about his biking with some friends, and about his plan to get into university. Now he had really started to live his own life.

Maybe I gave David something. But I also learned that one…without any words—can reach out to another person. All it takes is a hug, a shoulder to cry on, a friendly touch, and an ear that listens.

    Allan Guei, 18, was a star basketball player at Compton High School in the Los Angeles area before he graduated last month. His good grades made him eligible for an unusual competition: A free-throw contest in the Compton High gymnasium. The top prize: ＄40,000 in scholarship money.

    Guei, whose parents immigrated to the United States from the Ivory Coast, knew how much that financial aid could mean for his family. He was also feeling a fair share of pressure as students and teachers crushed into the gym to watch Guei and seven other randomly compete against each other.

    Guei won the free-throw contest by one basket and netted the ＄40,000. But it's what he did next that's truly astonishing.

In the weeks following the March free-throw competition, Guei learned that he'd scored a full-ride basketball scholarship to California State University—Northridge. NCAA(全国大学生体育协会)rules allowed Guei to accept the athletic scholarship and also keep most of the ＄40,000 he had won.

    But Guei couldn't stop thinking about the seven talented runners-up from the free-throw contest. They, too, had dreams and very real needs. So, he asked Principal Jesse Jones to make a surprise announcement at Compton High's graduation ceremony: Geui wanted to donate the ＄40,000 to the other seven students.

    “I've already been blessed so much and I know we're living with a bad economy, so I know this money can really help my classmates,” Guei said in a statement. “It was the right decision.”

    Guei elaborated on his decision to give the money away in an interview with ESPN(体育电视网): “I was already well taken care of to go to school, to go to university for free… I felt like they needed it more than I did.”

    Three years ago I worked for a few weeks as a doctor in a new dental clinic(牙科诊所）at Victor Harbor to the south of Adelaide and an hour further away than my usual workplace. My first day there was a driving to a new clinic and getting used to the clinical environment.

    As it was all new to me, I took off my rings: my wedding ring, and one that was an anniversary(周年纪念日)gift from my husband. I put them in a tissue(纸巾)and placed them beside my computer. During my lunch break, I noticed the tissue and thought that it did not look very clean and threw it into the rubbish bin. I went about my work and my day went well; I met new patients and felt that I had been productive

    Driving home at the end of the day, just moments before I reach that were missing. I felt the heat in my body rise, my cheeks(脸颊)burning red. I felt sick to my stomach.

    I spat an hour or so making calls, trying to find my rings. The first people I called were and clinical leader and they gave me a few phone numbers for cleaners I got in touch with already who managed the leaning services for the clinic, and she told me that the bins had already been collected.

    I knew nothing could be done now. I had lost my rings. Bu after two or so hours, I received the most amazing phone cal. The cleaner had gone through the bins and found my rings! I was so thankful to her, someone who had taken the trouble to go through the bins-which is not a pleasant task-to find my priceless rings.

    I worked at that clinic the following day, so I bought chocolates to thank this wonderful person. Unfortunately I did not get to meet her as she was not at work that day.

    We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn't finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?

    According to Time, of course not, taste has little to do with quality of water.

    According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.

    "But it's most likely safe to drink," Norwegian expert Truls Krogh told Science Nordic. "If the water is covered and of good quality to start with, in principle it can last a thousand years. That's because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health."

    People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.

    However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.

    With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you're more likely to be ill.

    And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to "several health damage, including heart disease and cancer", Time reported.

    Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.
